  • Mir Working On A Mir-On-Wayland Nested Compositor Path, Broadcom DispmanX API Support

    In addition to Mir's other road-map items around replaceable renderers and hybrid graphics driver support, it also turns out the Canonical developers involved are working on expanding the graphics platform support.

    Longtime Mir developer Alan Griffiths of Canonical wrote a post on Tuesday about the graphics platform support. To date Mir has released support for the KMS/Mesa drivers, Mir-on-X11 as a development target, eglstream-kms platform coverage for NVIDIA's proprietary driver, and an Android target with libhybris going back to the original Ubuntu Touch / Mir days.

    The open-source MoltenVK is out with another new update based against the Vulkan 1.1.126 specification and allowing the Vulkan API to be used on Apple's macOS and iOS by mapping those calls to the underlying Metal graphics drivers.

    Tuesday's MoltenVK update brings support for VK_EXT_swapchain_colorspace / VK_EXT_hdr_metadata, support for Metal 3.0 driver capabilities, native texture swizzling support, support for compressed 3D images on macOS, additional color-space options support, Xcode 11.1 toolchain support, reduced memory usage in some scenarios along with memory leak fixes, and a variety of other Vulkan bits were tweaked or added for this Apple portability layer.

  • Balint Reczey: New tags on the block: update-excuse and friends!

    In Ubuntu’s development process new package versions don’t immediately get released, but they enter the -proposed pocket first, where they are built and tested. In addition to testing the package itself other packages are also tested together with the updated package, to make sure the update doesn’t break the other packages either.

    The packages in the -proposed pocket are listed on the update excuses page with their testing status. When a package is successfully built and all triggered tests passed the package can migrate to the release pocket, but when the builds or tests fail, the package is blocked from migration to preserve the quality of the release.

    Sometimes packages are stuck in -proposed for a longer period because the build or test failures can’t be solved quickly. In the past several people may have triaged the same problem without being able to easily share their observations, but from now on if you figured out something about what broke, please open a bug against the stuck package with your findings and mark the package with the update-excuse tag. The bug will be linked to from the update excuses page so the next person picking up the problem can continue from there. You can even leave a patch in the bug so a developer with upload rights can find it easily and upload it right away.

  • Boeing CEO Accused of Telling 'Half-truths' in 737 MAX Hearing

    The hearing, the highest-profile congressional scrutiny of commercial aviation safety in years, heaps pressure on a newly rejiggered Boeing senior management team fighting to repair trust with airline customers and passengers shaken by an eight-month safety ban on its 737 MAX following the crashes, which killed 346 people.

    "You have told me half-truths over and over again," Senator Tammy Duckworth told Muilenburg, questioning why the manufacturer did not disclose more details about MCAS's lack of safeguards. "You have not told us the whole truth and these families are suffering because of it."

    Duckworth said the pilots did not know enough about MCAS.

    "You set those pilots up for failure."

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
